We all know that a pig farm wants to make money, breeding is the most important, but according to the survey, the pig farm elimination rate is increasing year by year. Many farmers pay more attention to the health of piglets and the slaughter rate of piglets. It is not so important for sows, but in fact only the long-lived production life of sows can effectively guarantee the economic benefits of pig farms. So what are the main reasons that affect the production life of sows? How to extend the production life of sows?
First, the main reason affecting the production life of sows
1. Reproductive disorders
Reproductive disorders are the main cause of abnormal elimination of sows. Causes of reproductive disorders are diverse, contagious (swine fever, pseudorabies, parvovirus disease, etc.), but also non-infectious (young sows are slow in puberty, not estrus after weaning, and match Infertility, recessive estrus, endometritis, etc., there are genetics also caused by feeding management, feed mildew, environmental stress and other factors, mainly because sows can not be smoothly propagated, improper artificial births, etc., such as sows No estrus, miscarriage, stillbirth, mummies, etc.
2, Minhang eliminated the sow
According to the survey, 15% of the sow herds will be eliminated due to limp, making Minhang one of the main reasons for the elimination of sows, second only to breeding problems. Many breeding problems are also related to limp, such as fewer litters.
Second, measures to extend the life expectancy of sows
1. Prevent reproductive failure of sows and increase the production life of sows.
(1) Strictly implement the vaccination operation procedures to ensure the density and quality of the vaccination. During the pregnancy period (especially in the early stage), live vaccines should not be injected to prevent intra-fetal infection, and the pregnant sows should be isolated from the vaccinated pigs.
(2) Strictly introduce quarantine. Introduce isolation and quarantine, and strictly prevent poisonous pigs from entering the farm. It is strictly forbidden to introduce them into infected areas.
(3) Strengthen feeding management. In the feeding process, it is necessary to rationally configure the feed according to the nutritional needs of each stage of the breeding pig, to improve the nutrients such as vitamins and minerals in the diet, and to feed the high-energy feed to pay attention to the use of mildew. In particular, ensure the normal supply of mineral elements calcium, phosphorus, iron, copper, zinc, manganese, iodine, chromium, selenium and vitamin E to ensure the balance of limiting amino acids, especially lysine.
(4) Do a good job in environmental sanitation and strengthen biosafety measures. Establish a strict disinfection system, regularly disinfect the floor, walls, facilities and utensils of the pig house, keep the air circulation in the pig house, strengthen the winter heat preservation, summer heatstroke and cool down; strengthen the management of excrement and sick pigs. Harmless treatment of feces, milk, miscarriage of fetuses, placenta, amniotic fluid and dead pigs in sick pigs. Eliminate the vectors of rats, flies and mosquitoes, and prevent other animals such as dogs, cats, and birds from entering the barn.
2. Excessive growth of the hoof will not only cause problems with the hoof bone, but also harbor bacteria that can cause infection.
The hoof repair helps the sow herd to fully exploit its genetic potential. Correct hoof repair reduces the pressure on the hoof, which makes the hoof blood circulation smoother and reduces the pressure on the shoulder and related joints. This will not only improve the sow's feed intake, but also make the sow happier.
3. Adding proper amount of minerals to the sow diet to prevent the productivity of the sow.
Copper, zinc and manganese are the three minerals most needed by sows and are essential for the health and reproduction of sows. Manganese is essential for the maintenance of joints, tendons and overall bone density; zinc contributes to the healing of body wounds and has a good effect on the sole, heel and hoof wall hardness and toughness; copper maintains the health of connective tissue and white lines. One indicator of good performance in sows is the relatively small number of somatic cells in the milk they produce. The amount of somatic cells in sow milk fed with appropriate amounts of copper, zinc and manganese is lower, which results in less inflammation, overall healthier, and a corresponding increase in production performance.
The above is the reason for extending the life expectancy of sows and effective measures. A pig farm wants to make money, breeding is the most important, extending the life expectancy of the sow, and the benefits to the pig farm are relatively large. Finding the main reason that affects the production life of sows, symptomatic dosing, and solution can effectively extend the production life of sows. I hope the above can help pig farmers.
